I personally have never had luck with proping my cake at an angle. I put it up higher and sit on a lower chair (dinning room chair at a kitchen counter) and then do the CL while the cake is sitting level on my turntable.
That's how i did this one.

Me too! 
I've never had luck tipping my cakes at an angle either! I set my turntable on a filled ice cream bucket to give it height, then grab a stool so your cake is eye level. It's just tall enough to work easily, but short enough that I can prop my elbows up on the tabletop so my hands are steadier. Ditto on making sure it's something sturdy.
